Weld — Analytics & Data

What is Weld?

Weld is a fully autonomous ETL and reverse ETL platform that connects 300+ SaaS apps, databases, and ERP systems to your cloud data warehouse (BigQuery, Snowflake, Databricks, Redshift, PostgreSQL). It automates schema mapping, API versioning, and data quality checks, so you can deliver fresh, reliable data to AI agents, analytics tools, and operational systems without a data engineering team.

Who is it for?

Weld is built for marketing teams consolidating ad spend and conversion data, revenue ops teams unifying CRM and billing metrics, and small analytics teams without dedicated engineers. It is not ideal for organizations that require on-premise data infrastructure or real-time latency below 5 minutes on its Basic plan.

Real use cases

Marketing teams use Weld to join Google Ads, Facebook Ads, and HubSpot data into a single BigQuery dataset for cross-channel ROI reports. Revenue teams ship cleaned Stripe and Salesforce data back to their CRM using reverse ETL. Data engineers leverage dbt Cloud or GitHub integration to manage transformations with version history and CI/CD.

• 300+ prebuilt connectors — For Stripe, HubSpot, Salesforce, Google Ads, Facebook Ads, Shopify, QuickBooks, Klaviyo, and more.
• Automatic schema mapping & API handling — Detects schema changes, manages API versioning, and prevents breaking updates.
• SQL editor & AI Transform — Write queries in the browser or use AI-assisted transformations; connect BI tools like Metabase or Looker.
